BOTTLE-CLOSURE.

SPECIFICATION formingpart of Letters Patent No. 714,991, dated December2, 1902. Application filed June 11,1902. Serial No. 111,130. (No model.)

To all whom, it 17mg concern:

Beit known that I, GEORGE JUSTIN ADAMS, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn, in thecounty of Kings and State of New York, have invented a new and ImprovedBottle-Closure, of which the following is a full, clear, and exactdescription.

This invention relates to improvements in lo closures for bottles andsimilar packing devices for containing tooth-powder or other toiletpreparations, the object being to provide a closure comprising twocapped members provided with openings designed to register upon turningone cap relatively to the other, the tops of the caps being resilient orspring-yielding, so as to maintain a close connection when the movablecap is turned, thus preventing the accumulation of powder between thetop plates of the caps.

A further object is to provide a simple means for limiting the rotarymovement of the movable cap when in use, but permitting its removal whendesired.

I will describe a bottle-closure embodying my invention and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of a bottle with a closure embodying myinvention applied thereto. Fig. 2 is a vertical section of the closure.Figs. 3 and 4c are plan views showing the parts of the closure indifferent positions, and Fig. 5 is a plan view of the fixed cap.

The closure comprises a fixed cap 1, a portion of which isscrew-threaded, and on the lower portion of the cap is anoutwardly-extended flange 2, which engages on the upper portion of thebottle, as seen in Fig. 1. A movable cap 3 has screw-threaded engage- 5ment with the fixed cap, as clearly indicated in Fig. 2. The top plateof the fixed cap is provided with an outletopening 4, and the top plateof the rotary cap is provided with an outlet-opening 5. These openingsare designedv to be placed in register for the purpose of dischargingthe powder. When, however, no powder is to be discharged, the openingsare to be placed out of register by rotating the cap 3.

As a means for limiting the rotary movement of the cap 3 I provide itstop plate with a downwardly-extending lug 6, designed to engage in asegmental channel 7, formed in the top of the fixed cap. When placingthe cap 3 on the fixed cap, when the movable cap reaches nearly to itslowermost position and the lug 6 is engaging on the upper surface of thefixed cap the said upper surface will spring downward slightly until thelug passes into the channel 7. When the lug passes into the channel, ofcourse the top plate of the fixed cap will spring upward against theinner side of the top plate of the rotary cap. Upon rotating the cap 3until the lug engages against the end of the channel 7 the opening 5will he placed in register with the opening 4. By a reverse movement theopening 5 will be moved out of register with the opening 4, and thelower edge of the cap 3 engaging with the flange 2 will prevent the saidrotary cap from moving too far in this last-named direction.

During the movement of the rotary cap the top plates of the two capswill he held close together, so as to prevent powder from gettingbetween them.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent-- 1. Abottle-closure comprising a fixed cap having a spring-yielding top plateprovided with an opening and with an arc channel, and a cap mounted torotate on the first-named cap, having a spring-yielding top providedwith an opening and an inwardly-extending 9o lug for engagement in saidchannel.

2. A bottle-closure comprising a fixed cap having a threaded portion anda spring-yielding top plate provided with an opening and an arc channel,and a cap having a screw- 5 threaded portion engaging with the thread ofthe fixed cap,'the said last-named cap having a spring-yielding topplate provided with an opening and an inwardly-extended lug for engagingin said channel.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE JUSTIN ADAMS.
